| Research Abstract |
In pancreatic stellate cells (PSCs), we revealed that some subtypes of Toll LikeReceptor were found. Moreover, in the mRNA analysis for mRNA derived from a pancreatic cancer bulk organization, it became a bad prognosis in the FAS high quantity group, when the postoperative adjunct therapy was not being performed,. Furthermore, we revealed that PSCs subpopulation which expressed CD10 antigen, which shows specialization of a lymphocyte, has contributed to the malignant behaviors of a tumor. This evaluation for PSCs subtyping further progressed and found out a possibility that CD271 expression was related to a resistance factor to cancer cells, and a possibility that CD146 expression had controlled invasion of cancer cells. Moreover, macrophage preparative isolation from a tumor was performed by using magnetic-separation equipment, and it has expected to progress to the control mechanism elucidation of a cancer cell and stroma targetingspecific new medical treatment by the macrophages and mesenchymal cells in the future
